WASHINGTON WINDOW FRAME Application filed June 1, 1929. `Seria1'No. 367,701.

Oar present invention relates to improvements in window frames and particularly to the manufacture, construction, and assembly of parts of a wood window frame, door frame,

or other similar structure. As here applied the invention is exemplified in the box-like structure of the window frame in which the sash weights are enclosed and which structure forms the runways for the vertically moving or slidable window sashes. n

The primary object of our invention 1s to so construct the parts constituting the frame that theparts may be assembled on the job by the carpenter, with convenience and facility,

and the parts are so fashioned and related that they may accurately be fitted one to another and properly aline/d to insure the proper guides for the window sashes.

By the embodiment in the window frame of the features of our invention, a weather tight structure is provided, and the frame is braced and supported in such manner as to prevent warping of the parts, to insure durability, and to maintain the proper shape of 26 the frame for operation of the sashes without binding.

The invention consists in certain novel combinations and arrangements of parts as will hereinafter be more fully described and claimed. In the accompanying drawings we have illust-rated one complete example of the physical embodiment of our invention wherein the parts are combined and arranged according to the best mode we have thus far devised for the practical application of the principles of our invention.

Figure 1 is a view in elevation showing the exterior side of a window frame in which our invention is embodied. Figure 2 is an enlarged, detail, vertical sectional view at the head of the frame, as at line 2-2 of F igure 1. Figure 3 is a horizontal sectional view of a portion of the boX frame at line 3-3 of Figure 1 and indicating the position of the sash weights. Figure 4 is a sectional view in perspective showing a portion of one of the blind stops, or wood strips, one located at each side of the frame and one disposed in horizontal position at the head of the frame.

In order that the general arrangement and relation of parts may readily `beunderstood lWe have shown `iin Figure 1 the upper and llower sashes 1 and 2 the sill 3 of the window;

the upright face plates or outside finish 'boards 4, 4'.; and the exterior head portions 5 and 6 comprising the lintel plate and "top molding strip.

In lFigure 3 at the interior side of ythe frame the sashbox is shown with the interior Aface plate 7, andthe plaster or wall yfinish is indi-cated at 8, it being' understood that both boxes forming the .sides of the frame are similar in construction.

Twosash weights 9, 9, onefor each sash are indicated in the box of Figure 8, andthe up- `J and horizontal parting strips 13 connect the vertical part-ing strips 11, and in Figure 3 the outside and inside lining boards 14 and 15 respectively coact with the studding 16 and jamb 10 to form the enclosure or box for the guidance of the weights 9. The usual top, vertically arranged and horizontally extending header 18 is located between the lintel plate 5 and the header 17.

The parting strip or the blind stop is made up of three pieces, the two uprights at opposite sides of the frame enclosure and the horizontal piece at the head of the frame. These wood strips forming the blind stop are designated as 19 for the vertical stops and 20 for the horizontal stop, and in all cases the wood strip projects as at 21 to form a bead that coacts with the parting strip 11 in the formation of the sash-groove.

These blind-stop parts are each fashioned with a 1/g-round tongue on one side and a dovetail tongue Q3 on its opposite side, the former preferably being positioned a slight distance from the inner edge of the stop and the latter being located at the edge of the inner face or edge of the stop, and nails are used to fasten the blind stop to the j amb or to the head plate 1Q. The jambs and the head plate 12 are fashioned with 1/z-round grooves l extending their full lengths to receive the tongues 22, and the tace plates 4 and lintel plate 5 are fashioned with complementary dovetail grooves 24 to receive the tongues 28. By this arrangement and location of tongues and grooves the carpenter is guided in assembling the parts and mistakes are avoided; weather tight joints are effected; the parts are accurately` alined, and warping or displacement of parts are prevented.

Some parts, as the jambs 10, lint-el plates 5, and finish boards 4, may have duplicate grooves as 25, which not only prevent warping of the wood, but they enable the carpenter to select the position of the parts for insuring the most eiiicient joints between parts.

Having thus fully described our invention, what we claim as new and desire to secure by Letters Patent is The combination with a blind stop, having tongues of different cross sectional area at opposite sides, of a jamb having a groove complementary to one of the tongues, a face plate having a plurality of spaced grooves for selective co-action with the other tongue,

` and said face plate at its edge overlapping a portion only of the blind stop whereby a projecting bead is provided.

In testimony whereof We atiix our signatures.
